Dear lammps users,
I am doing a simulation of membrane filtration based on lammps with granular pair style. Wanna share some of my understanding below, could some experienced friends please help me check whether I misunderstand the contents or not?
- As the fluid phase of the feed solution contains too many solvent particles, so the fix lb/fluid may not be proper because it has to include all the solvents. It will take too long.
- Right now I am using “fix viscous+velocity gaussian” as a way to apply the damping force and Brownian motion on the solute particles. Is this a good way to do it, any other forces that I missed in the system?
- I read the manual, another way is "fix langevin". With this fix langevin command, does this include all the forces of the implicit solvent?
Besides, the fix viscous+velocity gaussian is no longer needed, otherwise, there will be repeated force.
- Any other ways of implementing the solvent in the system? any good examples for understanding?
